By Kim Ronan, LCSW, MPH, CST | AASECT Certified Sex Therapist | Beverly Hills, CA | About Kim
As a sex therapist working with couples in Beverly Hills and throughout California, I meet people every week who sit down and quietly ask the same question: “Why do we keep having the same fight?” They’re often worried that something is wrong with their relationship or, worse, that they’ve chosen the wrong partner. If that sounds familiar, I want you to know this first: repeated conflict does not mean your relationship is broken. In many cases, it means your relationship is growing.
This is where the developmental model of couples therapy becomes such a powerful guide. I use this approach often in my work because it helps couples understand why conflict happens, what stage they’re in, and how to grow together instead of apart. Rather than seeing conflict as a failure, this model reframes it as a natural part of love that deepens with time.
Let me walk you through how this works and why it may be the roadmap you didn’t know your relationship needed.
Why Repeating Conflict Doesn’t Mean You’re Failing
Most couples come to therapy feeling discouraged. They’ve talked things through. They’ve read books. They’ve promised to “do better.” Yet the same arguments keep showing up about intimacy, parenting, money, or emotional distance.
What I often tell clients is this: conflict repeats because relationships move through stages. Each stage asks something new of both partners. If one stage isn’t fully worked through, the relationship will keep circling back to it.
This idea sits at the core of the developmental model of couples therapy. Relationships are not static. They grow the same way people do. Each phase brings new stress, new needs, and new chances for closeness. When couples don’t realize this, they assume conflict means incompatibility instead of relationship conflict growth.
In therapy, relief often shows up quickly once couples understand that what they’re facing is normal and workable.
The Developmental Model Explained in Plain Language
The Developmental Model of couples therapy views relationships as a process of growth across five predictable stages. Each stage has a task. When that task is met, the relationship becomes more secure. When it isn’t, conflict gets louder.
This couples therapy approach does not focus on blame or quick fixes. Instead, it helps couples understand:
- What stage their relationship is in
- Why certain fights feel stuck
- How emotional needs change over time
- What growth looks like at each stage
Rather than asking, “Who’s right?” we ask, “What is this stage asking of you?”
That shift alone often softens tension and brings compassion back into the room.
Stage One: Symbiosis (Romance and Early Bonding)
In the beginning, love feels easy. Attraction is strong. Differences between each person feel exciting. Many couples look back on this stage and wonder, “what happened to our bond?”
This beginning phase is about connection, safety, and bonding. Partners learn how to be close and build trust. Conflict is often avoided here, not because it doesn’t exist, but because the bond feels fragile. So often, their differences are minimized or flat-out denied.
When couples remain emotionally honest during this stage, they build a solid foundation. When partners don’t speak up, when they have needs that go unspoken, or some boundaries stay unclear- those issues tend to surface later with more intensity.
In relationship stages therapy, this phase matters more than people realize. Early patterns often set the tone for how couples handle conflict later on.
Stage Two: Differentiation (Power Struggles)
This is the stage where many couples feel alarmed. Power struggles begin to show up in an effort to show “my way of thinking is the right way”. Differences feel scary instead of charming. Arguments will often be on repeat. This is a time when emotional distance or sexual tension may grow.
From a developmental view, this stage is not a problem; it’s necessary. Each partner is learning how to stay connected while also being themselves.
This is where relationship conflict growth shows up most clearly. The relationship is asking both people to:
- Speak honestly
- Set boundaries
- Stay present during disagreement
- Tolerate discomfort without pulling away
Without support, couples often get stuck in this stage. With couples therapy, this stage becomes a turning point instead of a breaking point.
Stage Three through Five: Practicing, Rapprochement and Synergy
The later stages of the Developmental Model move through Practicing, where partners explore individual identity and outside interests; Rapprochement, where they come back to each other with a stronger sense of self; and finally Synergy, where the relationship functions as a true team.
Across all of these stages, something steadier forms. Communication improves. Trust grows. Emotional safety increases.
They do this by alternating between their strong, differentiated self and the supportive “we” of their relationship. We call this a dance between the “I” and the “we”.
Let me be clear, in these stages conflict doesn’t disappear. It means conflict for a couple becomes less threatening. Partners know how to repair after they say or do something that hurts their partner. They understand each other’s triggers and needs more clearly so they can respond with empathy.
In couples therapy, I often see couples rediscover intimacy here, both emotional and sexual. Desire feels safer when partners feel understood and emotional safety is there to take risks and explore pleasure.
These later stages are the main goals of relationship therapy, and they build directly on the work done earlier.
Why Conflict Is a Sign of Growth, Not Failure
One of the biggest mindset shifts I offer clients is this: your conflicts are information.
Arguments point to unmet needs, changing identities, or stress that hasn’t been named yet. The developmental model of couples therapy helps couples listen to conflict rather than fight it.
Rather than asking, “How do we stop arguing?” we explore:
- What is this conflict trying to say?
- What growth is being requested here?
- What stage are we being asked to move through?
It doesn’t happen in one session but over time, when couples can see their conflict this way, shame often fades. Curiosity about their partner’s differences replaces fear that they will never have that bond again.
How This Couple’s Therapy Approach Works in Sessions
In sessions, I assess a couple’s relationship history. We look at early bonding, turning points, or their first “disillusionment”, and repeating patterns of avoidance or conflict. We identify which stage feels unfinished and what each partner needs to move forward.
This couples therapy approach includes:
- Emotional awareness and regulation
- Clear communication skills to express wants and desire
- Empathic listening to understand partner’s experience
- Deeper understanding of early childhood experiences and attachment styles
- Sexual and emotional exploration
Because I work as a sex therapist, we also talk openly about intimacy, desire, and connection topics that many couples avoid but deeply need. As a Licensed Clinical Social Worker (LCSW) with specialized training in sex therapy, I bring both relational and sexual health expertise into this work because the two are rarely separate.
Why This Model Supports Lasting Love
Quick fixes for couples often fail because they don’t address relational growth. The developmental model of couples therapy supports lasting change by working with how relationships naturally evolve.
This type of couples therapy gives couples a shared language. It replaces blame with a better understanding of themselves and their partner. And it helps partners grow side by side rather than pulling apart or stifling their autonomy.
For many couples I see, this approach to their relationship restores hope. They stop asking, “Is this relationship broken?” and start asking, “What is our next step?”
If you have been stuck in the same argument for months or years and wondering whether something is fundamentally wrong, I want to offer you a different frame. Conflict is not the opposite of love. In the Developmental Model, it is often love asking you to grow.
If you are ready to understand what your relationship is actually asking of you, I would be glad to help. Reach out to book a session in my Beverly Hills office or online anywhere in California.
